has other not common former name. From the examination of the lectotype of Cerithium tuberculatum Lamarck, 1822, this two taxa are conspecific and that Lamarck's name has priority. However, Lamarck's taxon is a secondary homonym of Strombus tuberculatus Linne", 1758. Bruguière (1789:15) subsequently combined Linnets name, tuberculatus, with the genus Cerithium. The next available and valid name is Vertagus schroteri MCrch, 1852, of which the holotype is conspecific with Lamarck's Cerithium tuberculatum and which has the same type locality. The little-known name, schroteri, has never been applied to this species by subsequent authors. Cerithium caeruleum Sowerby, 1855 is the next available name and the one commonly used for this species. References External links Animal Base Cerithiidae Gastropods described in 1855
